' Letters Patent No. 100,27 2, dated March 1, 1870; autedted February 16, 1870.

IMPRCVED RAILWAY-CAR COUPLING The Schedule referred to in theseLetters Patent and makmg part o! the same To all whom lit may conce/rn Be it -known that I, J om: W. H. DoUBLEn, of Ghicago, in the county of Cook, and State of Illinois, have invented'a new and useful Improvement in Car Coup-- lers and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings and the letters and gures marked tl1ereon,.\vhich forni apart of this specification, andin which- Figure 1 represents a sidi` elevation of my invention Figure 2, a bottom view of the same; and

Figure 3, an end vew,look ing at the end of the car.

The nature'of my inventionconsists in apar-coupler, in which a horizontalhmik hooks automatically to a vertical pin, and couples the cars as they come together; also, in the combination with said hook, of a lever and spling for operating said hook; and, also, in

' the device hereafter specified, whereby the coupler is u'ncoupled by moving the rod or piece to which the spring is attached without overcoming the tension of the spring.

It further consists in attaching to the ordinary linkand-pin coupling an independent coupler, that couples thee-ars bebw the bumpe`r-heads.

To enable those skilled inthe art to understand how to manufacture and vuse my invention, I will proceed to describe the same with part-icularity.

. The ,saine letters of 'reference refer to the corresponding parts in the di'ercnt igures; vIn the annexed drawings- -A represents the ordinary railway-cars, and

B, the ordinary link-and-pin bumper-heads.

C C are pins which. extend through the bumpers to the piece D belowlthe bumpers.

The piece D is attached to the bumper and is braced by the uprightpiece E. Y

There is a sleeve, F, on the'jpin 1C, which serves to strengthen the 15h., and to which the coupling-hook H is attached.

The lever arm I is also attached to thgsame sleeve.

J is a rod suspendedbeneath the car 1u hangers K in such a manner 4that it can be moved laterally as hereafter specified.

There is a sliding block, L, on this rod, through which the arm-lever I passes, the sliding block being held in place by the springs P.

The coupling-hook H and the arm-lever I are firmly attached to the sleeve F, and turn with it, and the hook is keptv in a position to 'couple by means of the arm land springs P, the springs P allowing itto give to pass by the coupling-pin as the cars come together,

and keep it coupled by holding the arm-lever I in the position shown in fig. 2, when itis coupled.

There is an arm, O, attached rigidly to the rod J that rests in a notch in the hanger Q, and keeps the rod from moving laterally; but when it is desired to unccuple the cars, the said arm O israised from its place in the hangers Q, and the rod moved laterally, which vibrates the arm I and swings the coupling-hook H and uncouples the cars. By moving the rod J in this way the springs P are also moved,` and the car is uncoupled without over-A coming thevtension of the springs l, which keep the car coupledwhen the rod J is in the position above designated.

There can be a hook on the sleeve on each couplingpin G, but one hook is suicient for coupling the cars together. Y

lhc ordinary coupling-link can be used if desired, the hook-coupling above described not interfering with it in the least.

It will be observed that by placing the hook-coup- 1ling belowft-he'hnmper it'gives room to use long pins, and the cars will couple 'irrespective of the difference iu height between the cars.

My car-coupler is simple, cheap, not liable to get out of repair, is easily nncoupled when desired, and

- coupler, substantially furthe purpose specified.

2. The arm-lever I and springs P, when constructed and arranged to operate the coupling-hook H, sub stantially. 'as and for the purposes specified.

"3. The piece D, bumper B, and hook H, when constructed and arranged substantially as and for the purposes specified and shown.

4. The sleeve F, when constructed and arranged so as to strengthen the coupling-pin, substantially as described and specified.

5. The combination of the ordinary link-and-pin bumper-head and hook-coupler above described, when so constructed and arranged that either or both can be used for coupling the cars, substantially as specified 1and shown.
